Finite Element Modelling of RC Silo subjected to Thermal Loads
Silos are commonly used for storage and subjected to static and dynamic loading conditions such as gravity load, granular infill pressure, thermal load due to storage material, wind as well as earthquake loads. The design of silos is primarily governed by the properties and physical condition of stored material. As the density, flow and frictional properties of grains, cement, coal, carbon black, etc. vary widely and temperature of storage material also varies, resulting in fluctuation of thermal stresses in different parts of the silo structure, leading to material failure. In the present study, a numerical approach has been presented to identify the failure patterns in an RC cement silo. A three-dimensional finite element model of the silo has been modelled using ABAQUS software. The Concrete Damage Plasticity material model was employed to simulate the material behaviour of the concrete. The critical stresses in the wall of silo, including its inner conical potion, were determined. The lateral deflection in the silo wall along the height, with different occupancy levels of cement material, was observed and compared at normal as well as elevated temperature conditions.
